That's the box I write this from. It's experimental now but in theupstream kernel. Distros want to support more than 15 partitions, sothat will happen sooner than later.

And you may talk to the wrong rtc device, if you use static nodes, andso on. There are just too many things that can go wrong, and distrosthat don't have a very limited set of hardware, can not take the riskof a static /dev. They don't have this today, and will not go back toit. That's why we are coming up with this.

Sure, but you still have the transition to the tmpfs /dev, and duringthat you are very limited in what you can do, and this addressesdevtmpfs.
